LED performance can vary widely and is a function of the LED chip quality, the LED package, and all of the materials and manufacturing steps used in the process of making the device. The LED datasheet is the primary way to initially identify the performance capabilities of the device.
The color temperature determines the light color of an LED lamp. This color is indicated in Kelvin and results in how we perceive the emitted light. Warm light colors look very cozy, whereas cold white lamps often look bright and uncomfortable. In this guide you will find all details about the color temperature and the Kelvin specification.
When designing with LEDs, it is necessary to use the characteristic data provided with each product along with the LED product specifications. This section explains how to read typical characteristic data.
LED colors are often specified in "nm", or nanometers, which is the wavelength of the light. The wavelength given is the wavelength at peak output. LEDs are not perfectly monochromatic, but rather produce a range of wavelengths over a small region of the spectrum.
18 wrz 2024 · Kelvin (K): The unit that measures the color temperature of light. It determines whether the light appears warm (yellowish) or cool (bluish). Watts (W): The unit of power consumption. Unlike incandescent bulbs, watts in LEDs do not indicate brightness — they represent energy used.
The rise of LED lighting is driving a significant transformation of the lighting industry. LEDs can provide a palette of millions of colors and dynamic effects that conventional lighting cannot match in terms of design, scene-setting and ambience.
This number will help you decide how much voltage your circuit will need to supply to the LED. If you have more than one LED connected to a single power source, these numbers are really important because the forward voltage of all of the LEDs added together can't exceed the supply voltage.
